WebSocket Acceleration Driver
WebSocket Acceleration Strategy
Title:
WebSocket Acceleration for Real-time Market Data Processing (FMZ Quant)
Description:
This strategy optimizes the use of WebSocket connections to accelerate the real-time data processing for multiple exchanges in the FMZ quant trading platform. By leveraging WebSocket connections for deep order books and trades, this code significantly reduces latency in fetching market data and enhances performance, particularly for high-frequency trading (HFT) systems.
Key Features:
- Multi-exchange Support: This strategy supports Binance, OKX, Bybit, Bitget, and other exchanges via WebSocket, ensuring a faster and more reliable data feed compared to traditional REST API polling.
- Customizable Subscription: It allows subscription to specific market channels (depth, trades, etc.) and processes the received data efficiently for immediate use in trading strategies.
- Advanced Error Handling: Built-in error tracing and WebSocket reconnection mechanisms ensure the reliability and continuity of the data feed.
- CRC32 Checksum Validation: For exchanges like OKX, the code integrates a CRC32 checksum validation to ensure the integrity of received order book data.
This WebSocket-based solution replaces the traditional API polling with real-time updates, making it ideal for traders who need to minimize latency and maximize market responsiveness.
How to Use:
- Initialization: Use
$.setupWebsocket()to initialize WebSocket connections for your target exchanges. - Subscription: The system automatically subscribes to relevant channels (depth, trades, etc.) for the symbols you are trading.
- Data Retrieval: Market data (depth and trades) is processed and returned by calling
GetDepth()andGetTrades(). These functions automatically utilize the real-time WebSocket data if available. - Error Handling: The strategy includes a trace mechanism to log connection and data errors, and automatically attempts to reconnect when connections drop.
This script is designed to run on the FMZ quant platform, providing fast, reliable, and scalable access to market data across multiple exchanges.
javascript
function main() {
$.setupWebsocket()
while (true) {
exchanges.map(e=>{
Log(e.GetName(), e.GetDepth())
Log(e.GetName(), e.GetTrades())
// support custom and auto subscribe Eg: e.GetDepth('ETH_USDT')
})
EventLoop(100) // trigger by websocket or use Sleep control delay
}
}
// @ts-check
$.setupWebsocket = function (main_exchanges) {
let crc32 = function (r) {
for (var a, o = [], c = 0; c < 256; c++) {
a = c;
for (var f = 0; f < 8; f++) a = 1 & a ? 3988292384 ^ a >>> 1 : a >>> 1;
o[c] = a
}
for (var n = -1, t = 0; t < r.length; t++) n = n >>> 8 ^ o[255 & (n ^ r.charCodeAt(t))];
return (-1 ^ n) >>> 0
}
